There are several methods of biomass conversion, including hydrothermal liquefaction (HTL). The implementation microwave technology in the HTL process is still new, especially on conversion marine into bio-crude. In this work, macroalgae Chaetomorpha sp. was used as feedstock to produce phenolic-rich bio-oil through microwave-assisted HTL. abundantly found Malaysia, creating a green tides issue...

Abstract The palladium (Pd)-catalysed reaction has attracted much attention, making Pd the most valuable of four major precious metals. Several different forms can be used as a catalyst; nanoparticles (NPs) have advantage high surface area:volume ratio. Since chemical production NPs is not environmentally friendly, biological synthesis interest grown. However, mechanism remained unknown in seve...

A simple green method for the synthesis of silver nanoparticles (AgNPs) using the natural isolated orsellinic acid compound has been investigated for the first time. The present work describes a one-step functionalization of AgNPs using orsellinic acid as a reducing agent to convert Ag+ cations to AgNPs. This process eliminates the use of external toxic chemical reducing agents to provide a com...

To assess human exposure to aluminum (Al) from tea, the total Al contents in different teas (green tea, black tea and oolong tea processed with same fresh leaves) and the leaching of Al from these teas were analyzed, and the bio-accessibility of Al from these teas and their infusions was evaluated under simulated gastrointestinal condition. The results showed that green tea contained a high lev...

For the first time lactic acid was applied as an efficient and green catalyst for the one-pot three-component synthesis of amidoalkyl naphthols via the condensation between arylaldehydes, 2-naphthol and amides or urea under thermal solvent-free conditions in good to excellent yields. We have demonestrated a mild and efficient eco-friendly tandem synthesis of amidoalkyl naphthols using lactic ac...
